Abstract：The assembled laminated floor slab is an assembled monolithic floor slab made of prefabricated concrete sub-slabs and cast-in-place reinforced concrete layers laminated together.The production process and performance characteristics of assembled laminated floor slabs,steel floor joist slabs,fibre cement board floor joist slabs,and fine stone concrete non-demolition reinforced truss floor joist slabs are comparatively analyzed.The analysis focuses on the process characteristics and performance of the fine stone concrete non-demolition steel truss floor joist bearing plate made with high Bailey's sulphated aluminate cement.High Bailey's sulphated aluminate cement fine stone concrete base plate has fast hoisting speed,short demoulding time,low-temperature free steaming and demolition-free moulding.The base plate has smaller density,small shrinkage and deformation,high compressive strength,small water absorption rate,and large span.
